Most errors occur when students take an idiom literally.
LBL Hack: Always look for the 'mental image' the words create instead of the individual words themselves.
Idioms often come from specific historical contexts (Navy, Sports, Mythology).
LBL Hack: If you know the 'Why', you never have to 'Ratta' (memorize blindly).
Idioms are easier to remember when grouped by themes.
Watch for prepositions and intensity words.
